[the installments are designed to enable you to progress on your own – so you are not tied to the program in any way, but rather fully capable of managing your own recovery]
It’s much like anything else with the human body – it will adapt. If you stop going to the gym, you loose muscle. If you stop running, you loose endurance. If you do lots of close-up without any preventative efforts, you will get myopic.
In essence, you will just use the last habits you acquired when you were working on 20/20 (and possibly even 20/15 or better), to keep your eyes healthy.
As for your current glasses – look at the Snellen, and see which line you can read. If you can see 20/20, then, yes.
Small caveat here is that your natural 20/20 vision is better in terms of quality, than what you see through a lens. This is why lenses for professional cameras can cost many thousands of Euros (or dollars) – excellent optical quality is difficult to achieve. Also with glasses you have less peripheral vision, that border that is always in your field of vision (from the lens), dirt on the lens, etc.
It is questions like this I like the forum for.
Reality is that something close to 90% of questions come from individuals who are not in the paid program, and therefore usually not in the forum. I will try to remember to bring relevant topics here as articles more often, so you too can read the interactions.
Meanwhile though, a few of our free course participants have made it to sharing their results, and have requested free forum membership. So we may have some new participants to the dialog with us, starting very soon.
I’m really quite excited to see how this will work. My hope is that they genuinely benefit from the free course, and add to the dialog here. And of course, hopefully some of our long time readers and forum participants will chime in with feedback and comments as well!
